fiClaims. (01.257450) v j The invention is directed to a unitarystructure designed primarily for the purpose of permitting thesimultaneous cooling and the selected drawing off of one or severalfluids.

It has been heretofore proposed to provide for the simultaneous coolingand drawing ofi of one or several different kinds of liquids withoutintermixing, such previous structures involving helicoidal channelsforming distinct superimposed passages closed by a casing wall, with'thesuperimposed passages independent of communication and connected withthe feed and evacuation pipes, the cooling mixture being placed withinthe core. These channels of previous devices were formed in cylindricalwalls of different diameters, with the core in step form and fitted in acasing of corresponding shape. These constructions involved seriousdrawbacks in the commercial development, the necessary deformations ofthe cast metal rendering the subsequent working diflicult and expensive.

The primary object of the present invention is to provide a unitarydevice lacking the disadvantages of the previous devices and involvingmore particularly the provision of channels in cylindrical surfaces of asectional core, with the sections of the same diameter but otherwiseindependent, and fitting within a cylindrical casing of uniformdiameter.

The invention is more particularly illustrated in the accompanyingdrawing, in which:-

The figure represents a view in elevation, partly in section, of theimprovement.

The improved structure comprises a casing i formed immediately adjacentits lower end with an internal annular flange z", in which casing thereis arranged in superimposed relation a series of wholly independentrings or annular bodies a a a and a*. It is, of course, understood thatthe unit may be made up of any number of such annular bodies regardlessof the showing of four of such bodies in the present instance. Thelowermost ring a rests upon the flange 2", with an interposed sealinggasket 1, the remaining annular bodies being substantially identical andarranged in superimposed relation.

The uppermost ring a is provided with a thickened upper margin laterallyextended to form a flange h, and the casing i is correspondingly offsetat g to receive said flange, there being gaskets f interposed betweenthe respective bodies and between the flange h and horizontal portion ofthe offset 9. The meeting faces of the respective rings are preferablyformed to interfit, one such edge being formed with an annularprojection d,

and the other such edge with ach annel e in which is fitted the sealinggasket 1. A retaining plate' I, either as a solid or spider-like plate,underlies the flange 2" at the bottom of the casing, and the lower endof the uppermost annular body is formed with a spider 7' having acentral opening in align-- ment with a corresponding opening inthe'platel to receive a securing bolt k, the head of which underlies theplate Z and the threaded end of'whic'h is extended above the spider 7 toreceive a'nut for securing all of the bodies in fixed relation withinthe casing. u

This construction provides for the convenient removal of the bodies andtheir equally convenient reassemblag'e, as .will be evident. Each of thebodies is substantially of identical formation, so far as the coolingeffect of the fluid is concerned. That is to say, each body is formed inits exterior surface with a helicoidal channel b which originates in theupper portionof the particular body and terminates at the lower portion.there-'- of. Each channel is wholly independent'of and without anycommunication whatever with the similar channels of the remainingbodies. The channels of the respective bodies are fully open on theirouter sides, so far as the body is concerned, and are closed to formfluid .conduitsby the wall of the casing r Each body is provided withmeans by which the fluid to be cooled may be introduced and 85:1?withdrawn. For example, the uppermost annular body or ring a isinteriorly provided with a short length of tubular construction 1 openat the top and closed at the bottom and formed immediately above thebottom with a lateral port which directly communicates with the extremeupper portion of the channel b in said annular body or ring (1 Acorresponding tubular element 2 extends within the upper body, beingclosed at its lower end and open at its upper end, and communicatingthrough a lateral opening with the extreme lower portion of the channelb of that body or ring.

The second body a is correspondingly provided with inlet and outletconduits 3 and 4. The third body a has similar inlet and outlet conduits5 and 6, while the fourth body a has similar inlet and outlet conduits 7and 8. In each instance, the conduits are of pipe-like form connected tothe body with which they communicate and extend upwardly into the planeof the upper flange h of the uppermost body. Here they may beconveniently formed for the connection of pipes or other removableconduits for the inlet and outlet of the fluid to be cooled.

It is, of course, understood in this connection that the respectiveinlet and outlet conduits 1, 2, 3, 4, 5, 6, 7 and 8 are so relativelyarranged as to avoid interference one with the other in theirlongitudinal projection through the interior of the hollow annularbodies.

The respective annular bodies or rings are completely sealed one againstthe other, so far as the fluid channels are concerned, and thus providea convenient unitary structure which in the instance shown will providefor the independent cooling of four distinct fluids, any one of whichmay be admitted or withdrawn without regard to the other of such fluids,though obviously all such fluids or any number thereof may besimultaneously admitted and simultaneously withdrawn. This provides forthe selective admission, cooling and withdrawing of one or any number ofthe independent fluids within thev capacity of the constructionprovided, such ad mission and withdrawal being independent in point oftime or simultaneous at will.
